The value of square root -9 is not -3 because ——apex

Because you cannot do they square root of a negative number and obtain a natural number. The result should be an imaginary number, containing the letter "i".

The value of square root -9 is not -3 because -3 multiplied by itself is a positive 9.

The correct square root of -9 would be 3i.
